This shift is driven by safety concerns, electromagnetic compatibility, system stability, and the evolving needs of modern. Grounding is a mechanism to protect distribution equipment and people under normal operating conditions, abnormal operational (overcurrent and overvoltage) responses, and hazardous conditions such as shocks. This helps to reduce the potential difference that exists between conductive parts and the earth. Equipment Protection: Grounding protects substation. First, we review and compare medium-voltage distribution-system grounding methods. Knowledge of the various types of system grounding and performance characteristics is critical when designing or operating an electrical system. System grounding falls into 3 general catego-ries: solidly grounded, ungrounded, or resistance grounded, with there being diferent subcategories of resistance grounding.
